Patent DE-3911236-A1 (DE)
Inventor: SPANNHAKE DIETER DIPL ING
IPC: H04N5/10
Filed: 1989-04-07
Abstract: A method and circuit for deriving line (H) and field (V) held frequency sync pulses from a three-level sync signal of a HDTV signal involves deriving from a three-level sync signal (a, a') a two-level pulse signal (b) by separating the sync signal components located at roughly half the negative peak value. From the leading edges of the two-level pulse signal there are produced first gate pulses (c), whose duration is approximately three times the duration of the negative part of the H sync component of the three-level sync signal. H sync pulses (d) are derived during the duration of the first gate pulses (c) from the trailing edges of the two-level pulse signal. In addition, by integration of the two-level pulse signal (b), including Venable pulses (JVV), second gate pulses (f) are produced, whose duration exceeds the line duration. From the leading edges of the derived H sync pulses (d), V sync pulses (g, h) for the second and first fields of a frame are derived during the time of the second gate pulses (f). <IMAGE>

Title: Device for treating water
Inventor: GROTHKOPP HARTMUT DR SC TECHN
IPC: B01J47/012
Filed: 1989-04-10
Abstract: The invention relates to a device having exchangeable and transportable ion exchanger columns for treating water containing truly dissolved substances for the elimination and/or recovery of the dissolved substances, preferably from washing waters of relatively small and medium-scale plants for surface refinement. The object according to the invention is achieved by, in a device comprising adjacently situated exchangeable and transportable ion exchanger columns, the connections of which to the feed lines and outlet lines are arranged in the head of the ion exchanger columns, a feed vessel, a pump and, if required, a prefilter, arranging the ion exchanger columns of a rotary plate above the feed vessel at about the same radial distance to the rotary plate axis. When an ion exchanger column is changed, only a few connections need to be detached. As a result of rotating the rotary plate, all ion exchanger columns advance by one place. By using ion exchanger columns having connections arranged in the head for the feed lines and outlet lines, the ion exchanger columns are immediately transportable after separation and closure of the upper ports with closure caps. Such ion exchanger columns can be impinged both from top to bottom and from bottom to top. For this purpose, only the connections need to be exchanged. <IMAGE>

Inventor: KYRIAKIS JOHN
IPC: G01B11/04
Filed: 1989-07-07
Abstract: To determine the speed and length of a continuously moving object such as a rod, strip, wire or cable 1 by means of an image recognition technique, or the recognition of another suitable characteristic of the object such as capacitance or inductance, the characteristic is measured at two spaced positions 2 and 3 in its path of travel and the correlation between the two measurement signals is determined. Given the distance D between the two positions and the time between the recognizable image or electrical characteristic of the object being identified at the two positions, the speed of movement of travelling object is determined. The length of the object is determined from the average of a plurality of speed measurements over a particular production run. <IMAGE>

Patent DE-3939190-A1 (DE)
Inventor: WAIZMANN FRANZ
IPC: F26B25/00
Filed: 1989-11-27
Abstract: The invention relates to a continuous dryer for web-fed rotary offset printing machines for drying printed webs of material, furthermore to the operation of such a continuous dryer during printing and blanket washing with checking of the gaseous and vapour proportions of ink, washing fluid and burner. 
<??>According to the invention, an IR radiation path (11) is arranged in the dryer in order to measure the main concentrations of the gas/vapour proportions located in the gas chamber using IR absorption. The process followed by the continuous dryer can thus be oriented to evaporation rates of the volatile components. 
<??>In the IR absorption measurement, spectral measured values of substance vapours of the offset printing ink appear during printing and of substances of the cleaning agent during blanket washing in accordance with their characteristic band position and intensity. 
<??>In the transition from printing to blanket washing, an immediate picture is produced of the curve of the gas/vapour concentration level corresponding to the band intensities. Depending on the concentration limit, intervention in the adjustment of the flow (4), heating (2) and ventilation equipment of the dryer or targeted metering of the cleaning agent are derived. 
<??>Deflagrations in the dryer are avoided due to the lack of delay time in on-line measurement in the case of rapid adjustment reaction or precalculated adjustment. 
<??>The changing batches of printing ink are checked in respect of their substance composition by way of the measured absorption values. 
<??>The burner adjustments (16) are likewise checked, e.g. via the CO band and fuel gas bands of the mixture.

Title: Yacht with device to counteract heeling over - which is formed by hinged flaps fitted in openings in keel
Inventor: LOIDL WALTER
IPC: B63B41/00
Filed: 1989-11-29
Abstract: The device which automatically counteracts the tendency of a yacht to heel over under the force of the wind.  The yacht is fitted witha keel (1) with a rectangular opening (2) and flaps (3) which. can be rotated about vertical axes which are fitted in these openings. The spindles of the flaps are connected to a leverr which has a weight fitted to its outer end.  When the yacht heels over this weight causes the lever to rotate and actuate the flaps.

Title: Induction generator with periodically screened excitation magnet - incorporates rotor bridge for screening pole pieces of induction coil to prevent reversal of its polarity
Inventor: SCHOLZ LUDWIG
IPC: H02K21/18
Filed: 1989-12-14
Abstract: The excitation magnet (1) rotates between the pole pieces (3) of the induction coil (2) and the stator bridge (4) which spans the poles of the magnet (1).
